A free-standing PLLA microchamber arrays films are proposed to deliver small watersoluble substances. Rhodamine B was completely released from PLLA microchambers in vitro within 13 days. Low frequency ultrasound damages PLLA microchambers and detaches a sufficient number of microchamber "caps" with prolonged exposure time. Free-standing printed PLLA microchamber arrays can be applied as endovascular stent cover for complementary pharmacological effects.
